As she often does, Gaga struck somewhat strained charactery poses for the cellphone 'selfies' alongside her adoring fans.

The star also tweeted a couple of
enigmatic photos from her rehearsal on Saturday, in which she wore a
black ballerina outfit and stood in the middle of a group of her
identically-clad dancers.

Lady Gaga is preparing for her
performance at Sunday's MTV Video Music Awards, where she plans to open
the show with her latest offering, Applause.

Anxious about the ceremony, she told JustJared:
'I’ve been rehearsing all week and I’m so excited. It’s been incredible
dancing and singing again, doing all the things I love, so I’m having a
really good time.'

But the Poker Face hitmaker, who
recently snared more attention by starting a Twitter feud with celebrity
blogger Perez Hilton, refrained from revealing too many details.

Reiterating how much she enjoys the element of surprise, she said: 'You can’t really expect anything. I’m always trying to create something that the fans won’t expect.'
